Brainwashed Then Woke Up To Find My Childhood Friend a Hero

Our party ‘Adventure’s Oath’ became A-rank at the youngest age. I was famous as their holy knight and shield. But war with the Demon King’s army began. We lost. I became bait to protect my comrades and got caught and brainwashed.

I came to on castle ruins. The nearby village was celebrating. An old man said the Demon King was defeated. He added excitedly, ‘The hero’s the swordsman from that S-rank party ‘Adventure’s Oath’! ’

The hero who beat the Demon King was my childhood friend?
